If you zoom from the biggest object, The Observable Universe (8.8 x 10E26 or 880,000,000,000,000,000,000,000,000m across), all the way down to the hydrogen atom’s proton nucleus (1.7 x 10E-15 or 0.0000000000000017m across), you will have zoomed in over 100,000,000,000,000,000,000,000,000,000,000,000,000,000x!
How big is the universe right now?
If inflation occurred at a constant rate through the life of the universe, that same spot is 46 billion light-years away today according to Ethan Siegel, writing for Forbes (opens in new tab), making the diameter of the observable universe a sphere around 92 billion light-years.
How big is the universe for kids?
No one knows the exact size of the Universe, because we cannot see the edge – if there is one. All we do know is that the visible Universe is at least 93 billion light years across. (A light year is the distance light travels in one year – about 9 trillion km.) The Universe has not always been the same size.
How large is the universe game? – Related Questions
Is the universe finite or infinite?
There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
Is the universe flat or sphere?
The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4% margin of error.
How big is the universe short answer?
The universe is believed to be ever expanding according to the Big Bang Theory. According to the current status, our universe is 93 billion light years in diameter. The light-year is a unit of length which is the distance travelled by light in one year.
How small is the universe?
Today, 13.8 billion years after the Big Bang, the Universe is 46.1 billion light-years in radius — in all directions — from our vantage point.
How big is the universe ks2?
The part of the Universe we can see is at least 93 billion light years across. A light year is the distance light travels in a year (about 9 trillion kilometres). So multiply 9 trillion kilometres by 93 billion and that’s how big the visible Universe is!
Which is the biggest thing in Universe?
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Located around 700 million light-years from Earth, the Boötes void was first discovered by American Astronomer Robert Kirshner alongside with his University of Michigan colleagues back in 1981, during a survey of galaxy redshifts.
What is the oldest thing in the universe?
Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
What is the rarest thing in the universe?
Ring galaxies, the rarest in the Universe, finally explained
Almost every galaxy can be classified as a spiral, elliptical, or irregular galaxy.
With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag’s object.
Which is first language in world?
Dating back to at least 3500 BC, the oldest proof of written Sumerian was found in today’s Iraq, on an artifact known as the Kish Tablet. Thus, given this evidence, Sumerian can also be considered the first language in the world.
What was there before the universe?
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.
How will the universe end?
In the unimaginably far future, cold stellar remnants known as black dwarfs will begin to explode in a spectacular series of supernovae, providing the final fireworks of all time. That’s the conclusion of a new study, which posits that the universe will experience one last hurrah before everything goes dark forever.
When did time begin?
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
Does something come from nothing?
Who created God?
We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.
Does nothingness exist?
There is no such thing as nothingness, and zero does not exist.
